FATIGUE TESTING APPARATUS FOR STENT USING TERFENOL-D

摘要

PURPOSE: A fatigue tester for a stent using a magnetostriction element is provided to evaluate an accelerated test by increasing beat frequencies applied to a stent, and to conveniently perform a fatigue test. CONSTITUTION: A fatigue tester for a stent using a magnetostriction element comprises first and second base members(110,120), first and second mounting units(210,220), and a magnetostriction element(400). The first and second mounting units are connected to the first and second base members. The magnetostriction element is formed in the top of the first base member, and generates vibrations. The generated vibrations are transferred to the first mounting units through the first base member. The vibrations are repetitively applied to stent specimens(M) installed between the first and second mounting units.
